Multi-element chelated selenium-enriched trace-element water-soluble fertilizer and preparation method thereof

Abstract

The present invention discloses a multi-element chelated selenium-enriched trace-element water-soluble fertilizer and a preparation method thereof, the fertilizer comprises chelated boron, chelated zinc, chelated manganese, chelated copper, chelated iron, chelated molybdenum, chelated cobalt, chelated magnesium, organic selenium, organic solvents and water. The multi-element chelated selenium-enriched trace-element water-soluble fertilizer adopts chelated boron and contains nine nutrients demanded for plant growth, and can satisfy the full-nutrition trace elemental demands for plant growth truly. The fertilizer is safe to plant growth, can be efficiently absorbed, is high in utilization rate and less in usage amount, and cannot lead to soil hardening and salt accumulation. The fertilizer can act on plant cell nucleuses directly, can repair plant truncated genes, can promote the absorption of nitrogen, phosphorus and potassium and can strengthen roots. The fertilizer can improve the stress resistance of plants and make plants recover from devastation more rapidly. Usage amount of macro-element fertilizers can decrease by 10-30% under long-term usage of the fertilizer. The fertilizer can promote early-maturing and increase the quality and yield of plants and shows great economic benefits.

Description

technical field [0001] The invention belongs to the technical field of industrial fertilizers, in particular to a water-soluble fertilizer rich in selenium and trace elements in a multi-element chelated state and a manufacturing method thereof. Background technique [0002] Water-soluble fertilizers are widely used in food crops, cash crops, fruit and vegetable crops, flower tea gardens and Chinese medicinal materials in agriculture, forestry, flowers and other fields. Existing water-soluble fertilizers are mainly macroelement water-soluble fertilizers and common trace element water-soluble fertilizers, and the existing soils generally do not lack macroelements, and the main factor affecting crop growth is the lack of trace elements, especially selenium, More than 70% of the soil in China does not contain selenium. The existing ones are generally supplemented by spraying outside the root, which has relatively poor absorption and slow effect, resulting in greater waste. Co...
